A pugnacious case for this position ("doing them a service by showing them how their writing will be judged") was made by DFW in his very long essay on English usage [http://harpers.org/wp-content/uploads/HarpersMagazine-2001-04-0070913.pdf http://harpers.org/wp-content/uploads/HarpersMagazine-2001-0...]. See the bottom of page 53, or see just the basic excerpt at: https://www.reddit.com/r/SRSDiscussion/comments/xp3i4/race_and_language_in_authority_and_american_usage/ https://www.reddit.com/r/SRSDiscussion/comments/xp3i4/race_a... . DFW, who of course did teach writing, got significant pushback in the letters the next month. There's no winning this particular debate.
